Features
Model LM Volume Blowers:
- Cast aluminum blower housing. A rugged appearance is a plus for OEM designers of heavy-duty equipment.
- All models are AMCA Type C spark resistant. With the addition of an aluminum wheel (available in most sizes), LM blowers are AMCA Type B spark resistant.
- Round inlets and discharges allow for easy slip or flanged connections to duct or pipe without the additional cost of square-to-round transitions.
- Arrangement 8 units come standard with shaft/coupling guards.
- Arrangement 9 units come standard with belt guards.
Model LMF Volume Blowers:
- Cast aluminum housing with integral cast discharge flanges for easy direct mounting to motors and cabinets.

Benefits
- Spark Resistant: Model LM & LMF are standard with cast aluminum blower housings and steel, multivane wheels making them AMCA Type C spark resistant. With the addition of an aluminum wheel (available on most models), they become AMCA Type B spark resistant. Much less expensive than fabricated aluminum fans.
- Easy Pipe or Duct Connections & Mountings: LM Models have round inlets and discharges for easy slip or flanged connections to duct or pipe. They don’t require expensive square-to-round transitions. This also allows for easy flexible hose connections. LMF Models have integral cast-on discharge flanges making it easy to mount to cabinets, motors, frames, etc. Expensive mountings are not required.
- Attractive: Cast aluminum’s natural appearance adds to the aesthetics of the equipment it is mounted on. Provides a rugged appearance and it can be brushed, buffed, or colored by anodizing. It also has excellent paint adhesion. Excellent esthetics for OEM designers at no extra cost.
